Mental Epic is a mentalism effect where three covered predictions written on the top row of a slate or whiteboard are found to match those later written in a row below it.

It was created by Hen Fetsch, based on Peter Warlock's "The Taped Slate" (1944) [1]
and first PRESENTED (but not explained) in Pentagram, Vol. 6, No.7 (April 1952). It was later marketed in 1955 by his good friend Gene Gordon's magic shop.
